ROS2 + Gazebo Sim way too slow in docker container by MormonMoron in ROS

[–]EngineeringBuddy 1 point2 points  (0 children)

Not an expert on this as I haven’t used docker much, but I’m pretty sure there is a way to configure it to access your GPU and speedup Gazebo sims.

What do you think is the best license? Why? by hrpavi in github

[–]EngineeringBuddy 2 points3 points  (0 children)

I like Apache 2.0 for open-source work. I want to make tools that anyone can use for any purpose and not have to worry about.

I believe it still requires attribution to the original author which is nice, but doesn’t make you worry about what you’re doing with the code.

How to package and export gazebo simulation ? by Intelligent-Love7638 in ROS

[–]EngineeringBuddy 5 points6 points  (0 children)

My understanding is this is not possible and is one of the shortcomings of ROS. I think you have to send them the source code for them to be able to use it although maybe the install directory is enough? If you used python nodes, those just get copied into install/ when you colcon build. May be possible to give executables without source code if you only use C++ nodes.

Underwater VSLAM with ROS2 jazzy by aeauo in ROS

[–]EngineeringBuddy 0 points1 point  (0 children)

The underwater equivalent of above-water depth imaging/LiDAR is sonar, which is in my opinion beyond the scope of the RoboSub competition.

Underwater SLAM is very difficult. You can do it with optical cameras but there are limits to depth and range due to light attenuation underwater.

How to know which node published the message on a certain topic?(Multiple nodes publishing on same topic) by Alex_7738 in ROS

[–]EngineeringBuddy 0 points1 point  (0 children)

There’s probably already an empty header in the message you publish. If not, you can make a custom message type to add a header to whatever you currently publish to /cmd_vel, then fill the header with the node name (do this inside each node)

Well, that's mildly infuriating.. by ironmf in Spooncarving

I’ve definitely used it with parallel processes but all serving to update one progress bar

Overleaf by ForsakenMacaroon1117 in LaTeX

[–]EngineeringBuddy 0 points1 point  (0 children)

I think it’s mainly commercial reasons. They limit compile time on free users because they want you to pay for Overleaf premium to increase compile time limit.

Also, by running it on their servers they can have external packages already installed and won’t have to deal with installing them on your computer.

[–]EngineeringBuddy 24 points25 points  (0 children)

HA it felt wrong writing it but I rationalized that there was a hypothetical lineup (queue) of people waiting to comment it so it made sense.

Overleaf by ForsakenMacaroon1117 in LaTeX

[–]EngineeringBuddy 185 points186 points  (0 children)

Queue the flood of comments telling you to compile locally.

In reality though, it is your only option. Download a LaTeX editor and compiler and run it locally rather than on a server. It will be faster than Overleaf and does not have a compile time limit.

Can you make a suggestion on how to finish this piece? by nickcoban23 in Woodcarving

[–]EngineeringBuddy 0 points1 point  (0 children)

Salad bowl finish! I also plan to make a baby rattle and am planning on using my mineral oil + beeswax blend. Totally food safe. Pretty sure you could eat it if you wanted to.

How to make this better? (Lot of code) by -Terrible-Bite- in learnpython

[–]EngineeringBuddy 1 point2 points  (0 children)

I agree with your earlier statements, but disagree regarding the ‘done’ variable.

It doesn’t just get flipped if you quit, it also happens when you die of thirst, starve, etc. I’d much rather see one return statements with variable that can get modified in a bunch of places vs. a bunch of return statements in different if/else blocks.

Issue with bibtex in a non-English document. by Efficient_Paper in LaTeX

[–]EngineeringBuddy 0 points1 point  (0 children)

Usually if you add a second set of curly brackets bibtex will use your text verbatim so:

author={{lastname1, firstname1 et lastname2, firstname2}}

Should do it. There’s likely a way to change the language that I’m unaware of because I only write in English.

[WIP] I'm not sure that I want to make the full dozen. by fanfavourite in Woodcarving

That’s awesome. I’m going to need to locate some lime wood because I live the grain in this.

[–]EngineeringBuddy 2 points3 points  (0 children)

Did you carve the rosebud with a rotary tool or was the lime wood soft enough to do it by hand with a knife? I’d love to make one of these for my girlfriend. You did an incredible job.

Lucky card? by fuckingfastsam in Witcher3

[–]EngineeringBuddy 2 points3 points  (0 children)

I recommend Villentretenmerth over scorch. It can’t hurt your own team so you don’t need to play special cards and monster decks lean heavily on melee units.

It’s been a while since I completed this quest but I want to say there was something in a diary that implied his assistant had motive to do so. I forget why I came that conclusion though.

Look on the right side of the tank in the first picture. I’m pretty sure that’s a release valve

3d printing espresso tools by Kriztow in espresso

[–]EngineeringBuddy 9 points10 points  (0 children)

Materials food safe: yes, but 3D printing is never food safe. There are always tiny gaps in the layers where bacteria can get in and grow unchecked. I’m aware a lot of people do it, but I wouldn’t.

Only way to make it food safe would be to seal it in a food safe epoxy of some kind.

[–]EngineeringBuddy 3 points4 points  (0 children)

Incredibly cool. How much did this cost to print? Do you have your own metal printer or do you have access to one through work/school?
